I have one of these, the inputs are weird on mine, think player 1 punch is on player 2 side or something ?
I think mine also has a problem with jump .... it's on my 'to fix' list !
Actually @Alpha1 could you let me know what buttons are mapped to what on yours please, might help me sort mine out !
Back then it was all about staying alive as long as possible and the slowdown actually gave you a bit more time to think so it just felt like part of the game so probably isn't something you would necessarily remember.I have one also I got from Italy, haven't tried it yet but it really makes me wonder if I played these PCB's in my local arcade as I don't remember it slowing down at all and it was the game I played most in 80s, you'd hope to think you would remember that detail
